Take shelter from the cold at Ottawa’s only Winterlude partner that is nuclear fallout shelter!

Gather your friends and family and challenge them to our fun snowflake scavenger hunt. You’ll explore this massive bunker to find hidden snowflakes. Remember, the Bunker 100,000 square feet and spans 4 stories underground. That’s a lot of hiding spots. Then, kick back and relax with a warm cup of hot chocolate.

Did you know that when the Diefenbunker was in operation, the employees held an annual Winter Carnival?
We’re bringing you some of the indoor activities from the 60’s, 70’s and 80’s! You can take part in ping pong blow (yes that’s what it was actually called!), darts, bean bag toss, cards, paper airplane target practice, and more!

And what would a Canadian winter be without hockey?
Take part in our Mini Sticks Summit Series Hockey! Where you can practice shooting at our Soviet and Canadian goaltenders. Or if you have a group, you can have a 3-on-3 mini sticks game.
